Afterword to my book

The following is an excerpt from the final chapter of my book, Block by Block – The Historical and Theoretical Foundations of Thermodynamics, in which I took a step back to share a few insights and observations I unexpectedly gathered along the way. Happy the man, who, studying nature’s laws, Thro’ known effects can trace… Continue reading

How Shannon’s entropy met Clausius’s entropy in one illustration

I took a course from Edward Tufte a long while ago on the visual display of information and loved it. He challenged us to design single illustrations to tell our story, using the classic illustration (here) of Napoleon’s march to Moscow as a great example. I took on this challenge in creating illustrations for Block… Continue reading

Clausius, the gadfly, and the power of asking penetrating questions

As I shared previously (here), in 1857 Rudolf Clausius published [1] his derivation of the kinetic theory of gases in which he connected the world of moving and colliding atoms to the ideal gas law: PV = nRT. Based on his work, Clausius hypothesized that absolute temperature is proportional to the average kinetic energy of… Continue reading

About Me

Hi! I’m Bob Hanlon. After earning my Sc.D. in chemical engineering from the Massachusetts Institute of Technology and enjoying a long career in both industry and academia, I’ve returned to school, my own self-guided school, seeking to better understand the world of thermodynamics. Please join me on my journey.
